&amp;lt;p class=&amp;quot;step&amp;quot;&amp;gt;Photoshop CS or older:&amp;lt;/p&amp;gt;
&amp;lt;ol&amp;gt;
    &amp;lt;li&amp;gt;Tạo một layer mới v&amp;amp;agrave; chọn layer vừa tạo.&amp;lt;/li&amp;gt;
    &amp;lt;li&amp;gt;Sử dụng Lasso tool tạo một v&amp;amp;ugrave;ng chọn h&amp;amp;igrave;nh oval.&amp;lt;/li&amp;gt;
    &amp;lt;li&amp;gt;Đảo ngược v&amp;amp;ugrave;ng chọn (v&amp;amp;agrave; Select&amp;amp;gt; Inverse hoặc bấm Shift+Ctrl+I).&amp;lt;/li&amp;gt;
    &amp;lt;li&amp;gt;Bấm Shift+Backspace để mở c&amp;amp;ocirc;ng cụ Fill. Trong c&amp;amp;ocirc;ng cụ Fill, thiết  lập nội dung l&amp;amp;agrave; m&amp;amp;agrave;u đen rồi bấm&amp;amp;nbsp; OK.&amp;lt;/li&amp;gt;
    &amp;lt;li&amp;gt;Bỏ v&amp;amp;ugrave;ng chọn ( v&amp;amp;agrave; Select&amp;amp;gt; Deselect hoặc Ctrl+D).&amp;lt;/li&amp;gt;
    &amp;lt;li&amp;gt;Mở c&amp;amp;ocirc;ng cụ bộ lọc Gaussian Blur (v&amp;amp;agrave;o Filter&amp;amp;gt; Blur&amp;amp;gt;  Gaussian  Blur). Trong cửa sổ Gaussian Blur, h&amp;amp;atilde;y chắc chắn rằng &amp;amp;ocirc; Preview đ&amp;amp;atilde; được  chọn&amp;lt;span class=&amp;quot;short_text&amp;quot; id=&amp;quot;result_box&amp;quot;&amp;gt;&amp;lt;span title=&amp;quot;and adjust the
    Radius to blur the edges so  that a vignette is created.&amp;quot; style=&amp;quot;background-color: rgb(255, 255, 255);&amp;quot;&amp;gt;v&amp;amp;agrave; điều chỉnh  Radius để l&amp;amp;agrave;m mờ c&amp;amp;aacute;c cạnh&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt;.&amp;lt;/li&amp;gt;
    &amp;lt;li&amp;gt;Giảm opacity một ch&amp;amp;uacute;t. Đặt gi&amp;amp;aacute; trị opacity khoảng 75% sẽ cho ra kết  quả tốt.&amp;lt;/li&amp;gt;
&amp;lt;/ol&amp;gt;

&amp;lt;p&amp;gt;&amp;lt;span title=&amp;quot;Inside the
Channels pallet (Window&amp;amp;gt;  Channels), select the red channel.&amp;quot; style=&amp;quot;background-color: rgb(255, 255, 255);&amp;quot;&amp;gt;Trong  hộp thoại Channels  (Window&amp;amp;gt; Channels), chọn k&amp;amp;ecirc;nh m&amp;amp;agrave;u đỏ (&amp;lt;/span&amp;gt;red  channel)&amp;lt;span class=&amp;quot;long_text&amp;quot; id=&amp;quot;result_box&amp;quot;&amp;gt;&amp;lt;span title=&amp;quot;Inside the Channels

&amp;lt;h3&amp;gt;Bước 4&amp;lt;/h3&amp;gt;
&amp;lt;p&amp;gt;Với k&amp;amp;ecirc;nh m&amp;amp;agrave;u đỏ đ&amp;amp;atilde; được chọn, sử dụng c&amp;amp;ocirc;ng cụ Brightness/Contrast   (Image&amp;amp;gt; Adjustments&amp;amp;gt; Brightness/Contrast) &amp;lt;span class=&amp;quot;medium_text&amp;quot; id=&amp;quot;result_box&amp;quot;&amp;gt;&amp;lt;span title=&amp;quot;and increase the contrast.&amp;quot; style=&amp;quot;background-color: rgb(255, 255, 255);&amp;quot;&amp;gt;v&amp;amp;agrave; tăng độ  tương phản. &amp;lt;/span&amp;gt;&amp;lt;span title=&amp;quot;The higher you set
the contrast, the stronger the color effect  will be.&amp;quot; style=&amp;quot;background-color: rgb(255, 255, 255);&amp;quot;&amp;gt;Thiết lập độ  tương phản c&amp;amp;agrave;ng cao, c&amp;amp;aacute;c hiệu ứng m&amp;amp;agrave;u sắc sẽ c&amp;amp;agrave;ng được nhấn mạnh hơn. &amp;lt;/span&amp;gt;&amp;lt;span title=&amp;quot;I found that
increasing the contrast by 50 produced the  most realistic results.&amp;quot; style=&amp;quot;background-color: rgb(255, 255, 255);&amp;quot;&amp;gt;Đặt  độ tương phản 50 sẽ cho ra kết quả tốt nhất.&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/p&amp;gt;

&amp;lt;p class=&amp;quot;step&amp;quot;&amp;gt;&amp;lt;strong&amp;gt;Bước 5:&amp;lt;/strong&amp;gt;&amp;lt;/p&amp;gt;
&amp;lt;p&amp;gt;B&amp;amp;acirc;y giờ h&amp;amp;atilde;y chọn k&amp;amp;ecirc;nh m&amp;amp;agrave;u xanh(green channel) v&amp;amp;agrave; sử dụng c&amp;amp;ocirc;ng cụ  Brightness/Contrast  (Image&amp;amp;gt; Adjustments&amp;amp;gt; Brightness/Contrast)&amp;lt;span class=&amp;quot;short_text&amp;quot; id=&amp;quot;result_box&amp;quot;&amp;gt;&amp;lt;span title=&amp;quot;to increase the contrast by the same amount
you did in the previous step.&amp;quot; style=&amp;quot;background-color: rgb(255, 255, 255);&amp;quot;&amp;gt; để tăng độ tương phản. Bạn cũng đặt gi&amp;amp;aacute;  trị Contrast l&amp;amp;agrave; 50.&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/p&amp;gt;
&amp;lt;h3&amp;gt;Bước 6&amp;lt;/h3&amp;gt;
&amp;lt;p&amp;gt;Chọn lại RGB channel (Ctrl+~) để xem kết quả cuối c&amp;amp;ugrave;ng.&amp;lt;/p&amp;gt;
